This invention has reference to a puller for a contlnuous wire drawlng bench.

The invention has for its principal object movement to be applied through the puller to the drum or drums.

That the invention'may be more fully understood, reference ishad to the accompanying drawings forming part of this description, illustrating a preferred embodi ment of the invention, in which Fig. 1 is a partial plan, more or less diagrammatic, showing a continuous wire drawing bench and my puller applied to the flange of one of the drums;

Fig. 2 is a front elevat shown in Fig. 1; I

Fig. 8 is a detail showing the plied to the flange of a drum;

Fig. 4 is a detail in section of what is shown in Fig. 3;

Fig. 5 is a cross-section of a clamp to grip the wire and Fig. 6 is a sectional detail, as the same would appear on the line 6-6, Fig. 5.

Like characters of reference denote corresponding parts throughout the figures.

The drawing bench shown is for illustrative purposes only, and except in so far as the flanged drums are employed, forms no part of the present invention. is designated Aand includes two or more wire drums 0; having flanges a; drawing dies 6; wire guiding rollers 0, and the block ion of what is puller apd, together with the necessary and usual operating parts.

Preliminary to threading the machine with the wire to be drawn; the wire, which for convenience is designated B, is preferably p'ointed as at c, c and 0 see Fig. 5, in some suitable pointer, not shown, 'tofacilitate such wire being threaded through the the guiding rollers 0.

This bench successively smaller dies on the bench, and as it is threaded through eachdie, a clamp is caused to grip the end of the wire and the puller applied to the flange a of a drum a.

and the drums rotated several turnsto warp or coil the wire therearound, while between each drum the wire is passed over or around While I. have shown the wire B pointed with several successive reductions, this method of pointing need not be followed and only a single or tapered point provided thereon.

The puller comprises a yoke 1 with ends 2 and 3 of preferably unequal length, so that as the yoke is caused to embrace a flange a of a drum '0 the end 2 will lie on the inner sideof the flange a and the end 3 will lie on the outer side of the flange a, see Fig.

4. Then when tension is applied to the puller so as to cant the yoke on the flange of the drum, as shown in Fig. 3, a frictional grip is set up betweenthe puller-and the drum, permitting the puller to be employed as a crank'for manually manipulating or turning the drum to wrap or coil the wire therearoundl Release of the tension allows the puller to be released and easily removed or dropped from the drum. Thus the puller is arranged for quick slip on and off connection with the flange of the several drums.

Connected to and extending laterally from the end of the yoke 1 is a handle or handgrip 4, and connected to and extending laterally from the end 2 of the yoke 1 is an ear or lip to which is connected one end of al flexible member 6,the other end of which is connected to a clamp 7. This clamp includes the preferably tubular and conical shaped head 8 in which are located the separable jaws 9 backed by a washer 10 and a coil spring 11 against which the; washer bears and one end of which is secured in the head 8. The pointed end of the wire may be easily slipped through the head 8 of the clamp and between the jaws 9, then when pull is applied the jaws firmly grip the wire.

What I claim is 1. A puller for use in connection with wire drawing benches, comprising a member having a yoke portion arranged for quick slip on and off connection with the flange of a drum and adapted when cantedto frictionally engage such flange, means to'connect a wire with said member; and hand-hold to permit manual operation of said member. 2; A puller for use 1n connectlon with Wire drawlng benches, comprising a member having a yoke portion arranged for quick slip on and ofi connection with the flange of a drum and adapted when canted to frictionally engage with the sides of such flanges, whereby through manual manipulation of said member said drum may be roio tated, a hand'hold extending laterally from member having unequal sides, a hand-hold connected to and extending laterally from the longer side of said yoke and a connection for a flexible member extending laterally from the shorter side of said yoke.
